ABSTRACT

A method for recording input text that is input in an input field of a webpage, the method comprising: providing the webpage to a client device, by processing circuitry, the webpage comprising: (a) the input field, and (b) instructions executable by web-accessing software for recording the input text; and wherein execution of the instructions results in: identification of masking information in the input text, if any, the masking information being information in the input text to be masked; and if the masking information is identified, masking of the masking information prior to the recording of the input text, so that the masking information is masked when recorded.

TECHNICAL FIELD

The invention relates to a system and method for automatically masking confidential information that is input on a webpage.

BACKGROUND

Organizations that accept, process and store credit card information are required to comply with the Payment Card Industry Data Security Standard (PCI DSS) to ensure that the credit card information is not obtained by unauthorized parties. Accordingly, organizations that wish to record and play back a user's web session on the organization's website must ensure that credit card information that is input during the web session is masked prior to the recording thereof. It is an object of the present disclosure to enable an organization to automatically mask confidential information, for example credit card information, that is input in any input field on a webpage of the organization, prior to the recording of the confidential information, and without the need for the user to provide an explicit configuration for masking the confidential information.

References considered to be relevant as background to the presently disclosed subject matter are listed below. Acknowledgement of the references herein is not to be inferred as meaning that these are in any way relevant to the patentability of the presently disclosed subject matter.

PCI/PII Masking—WhosOn, available at https://www.whoson.com/explore/pci-pii-masking/?cn-reloaded=1 (captured on Nov. 25, 2018) discloses secure PCI/PII masking to help protect sensitive data shared by customers in a live chat session. This means that any credit card numbers typed inside a WhosOn chat session will be masked, helping a company meet strict PCI DSS security standards. Here's how PCI/PII masking by WhosOn works: From within the WhosOn client, the company can create rules to detect credit card number patterns. WhosOn can then run a pre-storage database procedure against each line of transcript. This allows masking where PII data is detected, or triggered warnings based on the company's settings. During chat transfers, a clean-up procedure can be executed. This will either create a new chat, or mask individual lines.

U.S. Patent Application Publication No. 2017/0186127 (Yu), published on Jun. 29, 2017, discloses a method and an apparatus for capturing a screen on a mobile device, the method including: receiving, at the mobile device, a screen-capturing request for a current interface, where the current interface includes first data, and the first data includes personal information; and generating, according to screen-capturing request, a screen capture image for the current interface, where the first data in the current interface is replaced in the screen capture image with second data which is predefined. This avoids the need to manually mask an image by starting a dedicated image editing tool to anonymize a screen capture image, thereby significantly lowering the relatively high technical threshold of anonymization processing, reducing the error rate, and improving the modification quality of anonymization. Moreover, the replacement is directly made to the image while the screen is captured without interfering with normal use of reading.

U.S. Patent Application Publication No. 2015/0363789 (Moran et al.), published on Dec. 17, 2015, discloses a system for providing Payment Card Industry (PCI) compliance for a contact center. The system includes a monitoring module configured to monitor a communication session between an agent and a customer. At least one image associated with the agent's computer screen is captured during the communication session.

Unlike typical analytics services that provide aggregate statistics, these scripts are intended for the recording and playback of individual browsing sessions.

U.S. Patent Application Publication No. 2008/0208579 (Weiss et al.), published on Aug. 28, 2008, discloses a computer-implemented method for session processing including identifying a type of data item that is presented to a user by a computerized system. A session in which the user interacts with the computerized system is recorded. A data item of the identified type is automatically detected in the recorded session. The recorded session is replayed, while refraining from presenting the detected data item in the replayed session.

U.S. Patent Application Publication No. 2018/0285599 (Praveen et al.), published on Oct. 4, 2018, describes methods, systems and computer program products for layered masking of data. A system receives content including personally identifiable information (PII). The system redacts the content by masking the PII. The system identifies the PII in multi-layer processing, where in each layer, the system determines a respective confidence score indicating a probability that a token is PII. If the confidence score is sufficiently high, the system masks the token. Otherwise, the system provides the token to a next layer for processing. The layers can include regular expression based processing, lookup table based processing, and machine learning based processing.

Attention is now drawn to FIG. 4 , a flowchart illustrating a first example of a sequence of operations carried out by a webpage provider 110, in accordance with the presently disclosed subject matter.

In accordance with the presently disclosed subject matter, webpage provider 110 can be configured to perform a webpage management process 400, e.g. using webpage management module 240.

For this purpose, webpage provider 110 can be configured to provide a webpage 130 to a client device 120, the webpage 130 comprising: (a) an input field 160 (e.g., within a web form 150), and (b) instructions executable by web-accessing software 140 for recording input text 170 that is input in the input field 160, wherein execution of the instructions results in: analysis of the input text 170 to identify masking information in the input text 170, if any, the masking information being information in the input text 170 to be masked; and if the masking information is identified, based on the analysis, masking of the masking information prior to the recording of the input text 170, so that the masking information is masked when recorded (block 404). For example, if a user of the client device 120 inputs masking information in an input field 160 that is not designated by the webpage 130 for obtaining the masking information, the masking information can still be identified by analyzing the input text 170.

In some cases, if the masking information is identified in the input text 170, execution of the instructions can further result in the automatic masking of text that is input in any of the input fields contained within a parent HTML element (the webpage 130, web form 150, web sub-form, etc.) that includes the input field 160 in which the input text 170 was input, absent an explicit configuration provided by a user of the client device 120 not to automatically mask the text that is input in certain input fields contained within the parent HTML element.

In some cases, the masking information can include part or all of a confidential number, being one or more of the following: a credit card number or a personal identification number. The instructions included within the webpage 130 can indicate the digits of the confidential number that should remain unmasked, if any.

In some cases, the confidential number can be validatable by a Luhn algorithm. It is to be noted, in this regard, that credit card numbers are generally validatable by a Luhn algorithm.

In some cases, input text 170 can be analyzed to identify a confidential number in the input text 170 by: (a) determining whether the input text 170 includes at least one instance of numeric text consisting of, with the exception of whitespace characters, if any, a first number of numeric characters; (b) if the input text 170 includes the at least one instance of numeric text, determining whether the first number of numeric characters is identical to a second number of numeric characters in the confidential number or is within a range of a possible number of numeric characters in the confidential number; (c) if the first number of numeric characters is identical to the second number of numeric characters or is within the range of the possible number of numeric characters, applying a checksum formula to a numeric value formed by the first number of numeric characters; and (d) if the checksum formula applied to the numeric value returns a positive result, determining that the at least one instance of numeric text includes the confidential number.

In some cases, the checksum formula that is applied to the numeric value formed by the first number of numeric characters can be a Luhn algorithm.

In some cases, the confidential number can be a credit card number, and the range of the possible number of numeric characters in the credit card number can be between twelve and nineteen, inclusive.

In some cases, input text 170 can be analyzed to identify a confidential number in the input text 170 by: (a) determining whether the input text 170 includes at least one instance of numeric text consisting of, with the exception of whitespace characters, if any, and hyphens, if any, a first number of numeric characters; (b) if the input text 170 includes the at least one instance of numeric text, determining whether the first number of numeric characters is identical to a second number of numeric characters in the confidential number or is within a range of a possible number of numeric characters in the confidential number; (c) if the first number of numeric characters is identical to the second number of numeric characters or is within the range of the possible number of numeric characters, applying a checksum formula to a numeric value formed by the first number of numeric characters; and (d) if the checksum formula applied to the numeric value returns a positive result, determining that the at least one instance of numeric text includes the confidential number.

In some cases, the checksum formula that is applied to the numeric value formed by the first number of numeric characters can be a Luhn algorithm.
